'Arrow's' Stephen Amell and Cassandra Jean welcome baby girl

"Arrow" star
Stephen Amell announced back in June that his wife
Cassandra Jean was pregnant with their first child. On Saturday (Oct. 19), he posted a picture of the new bundle of joy to his Facebook page (inset), writing, "
She came just in time for Amell Wednesdays."

He is referring to the fact that on Wednesday nights on the CW, viewers get a double dose of Amell, with Stephen in "Arrow" at 8 p.m. ET/PT and his cousin Robbie Amell on "The Tomorrow People" at 9 p.m. ET/PT.

Amell and Jean were married in December 2012. Jean is an actress and model who famously quit "America's Next Top Model" Cycle 5 when she refused to cut her hair even shorter than had already been done in her makeover. UPDATE: In a statement to Just Jared, a rep for the actor says, "Mavi Alexandra Jean Amell was born on Tuesday afternoon (October 15). Everyone is happy and healthy."
